Hi all , im setting up a new pond, I've had a 4 bay kockney koi filter for tge needs pond . I've got brushes and plenty and of k1 from the old filter , I believe k1 is usual positioned at the end off a filter , I was planing on having one chamber brushes , one chamber foam and 2 Chambers k1 , my question is can I make the first chamber k1 so I can use the filter flow to fluidis it , then brushes 2nd chamber , foam chamber 3, static k1 chamber 4 and then back to the pond , what is the down side off biolgical filtration with the fluidised bed first
Many thanks
